My invention relates to container closures.

and refersparticularly to container closures adaptedto be' employed with fiber, wood, or other'readily penetrable containers.

One ottheobjectsofiny inventionis a container closurewhich can be readily. and efiectively attached to a container bythe. insertion of prongs, or'hooks, carried by the closure member. I a i 110 Another objectof my invention is a device sirable and valuable features are possessedby the device of my invention as will be evident upon a consideration of my specification and its accompanying drawings.

'It is frequently desirable to attach metallic closures, or covers to containerscomposed of fiber, wood or other readily penetrable materials in such a manner that the closure member may be readily removed without injuring the container: 7 V

yflhis desirable result is difficult to obtain when the closureco'mprises ametallic member carrying apluralityof inwardly projecting hooks, or prongs, which arepressed inwardly Lot the container side during the 3 closed positionabecause it is practicallyvim-v possible to-withdraw the impressedhooks or prongs. m a a i Hence, in cases of this character, itisnecesitedto such containersas are to be completely emptiedas soon as opened and which are not to be retained as a storageifor the contents.

1 It is evident, therefore, that if a closure of er ease and facility than is a [saryto exert very considerable force totear 40 i this character can be so constructed as to have the valuable closure features which arel in cident to closures of thisiparticular;character and'at thesame time possesswthe property 7 of being readily removed Withoutmarring, or tearing, the c0ntainer,'it wouldibe agreat advance in theindustry and would enable their much wider'adoption. a a

The deviceof my inventionpossessesi these valuableattribut-es andiis .ofj su'ch construction as to, allow of its production with greatpossible with the present known devices} e a t 1 1 Thepresent known devicesofthischarace ter, as well asniy own,"areU,-shaped, being shaped with anjiexterior downwardly ex tended member, the lattercarrying the fastening hooks. The container Wall is placed between the two parallel elements of the device, the upper edge of the; container side supporting the-device, z y Theseidevices, therefore, have four membrs positioned angularly to eaoh other, two of the 'membersfbeing in, paralleli planes spaced but slightly from eachuother and one (5 of" the *members carrying a plurality of prongs o'r hooks. Experience has shown that itis practically impossible to drawadevice "ofthis character, or to economically produce itin anyothermanner and hence their com- '80 mercialization has been greatly retarded.

I have overcome this difficulty by produc iii-g the closureintwo separate elements, each readily made,andthen'combining these two elements. .Ii f. The prongs, or hooks,-ofthesedevices are most I economically produced by. stamping, or cutting, them out of the device itself and v t-henbei'iding theminto thefdesired shape. Whenhooks of this character arejforced into the container sidein order to fasten the clo; sure to-flthe container, itis impossible; toinsert a toolbeneathth einserted hooksjin order to withdraw them from their holding position, and, hence, they mustbeforcibly torn 9 from contact with the container, thus ruining thelatterQ, i 1 y 1 I have overcome" this difficulty by'forming an openingaroundone side, or both sides, of the prong, thus enablingthe insertion of a tool beneath the prong to bend it outwardly from its inserted position without tearing or marring the container.

The above-mentioned and other, valuable features of my device are clearly described and shown in the accompanying specification.

In the accompanying drawings illustrating modified forms of the device of my invention, similar parts are designated by similar numerals.

Figure 1 is a front view of one form of my device attached to a container.

Figure 2 is an enlarged front view of a portion of the device of Figure 1. V

Figure 3 is a section taken on the line 3-3 of Figure 2.

Figure 4 is a vertical section showing the use of a tool to remove a hook.

Figure 5 is a front view of a modified form of my device.

Figure 6 is a section taken on the line 66 of Figure 1.

The particular form of the device of my invention shown in Figures 1 to 4, inclusive,

. comprises a U-shaped container head having the base 10, the upwardly extended side 11 and the outwardly extended flange 12, the latter being capable of abutment upon the upper edge of the side 13 of a container.

The outer, or fastening, member of my de vice comprises the side 14 having the inwardly extended flange 15, the flanges 12 and 15 being attached to each other by spot welding 16, or otherwise.

The side 14 carries a plurality of bent fastening means or hooks, 17l8, 1718, out out ofthe side 14, and being outwardly extended before attachment to the container side 13, as shown in dotted lines in Figure 3. There is a cut-out, or opening 19, in the side 14 around each side of the hook element 17.

In operation, my container cover is placed over the upper end of the container, the flange 12 abutting upon the upper edge of the con tainer side 13, the side 18abutting upon the inner face and the'side 14 abutting upon the outer face of the container side 13.

The hooks 17-18 are thenpressed inwardly, preferably until the face of the hook element 17 is flush with the face of the-side 14, thus causing the cover to be firmly atfixed, or fastened, to the container and producing a non-leaking ointure therewith.

lVhen it is desired to remove the cover without injuring the container sides, a tool 20 is inserted through an opening 19 and under the hook element 17, and the hook forced outwardly by using the tool 20 as a lever and the side 14 as a fulcrum.

In the modified form of my invention shown in Figures 5 and 6, the hooks are of triangular shape 22, 23 and are directed downwardly instead of upwardly.

I prefer to have the hook portion 18 of each tongue positioned abovethe head base 10, thus giving rigidity to the container side 13 for the better insertion of the hook therein. The operation of my device is as follows: The device is placed upon a container side 13 as shown in the drawings, and the hook portion 18 of each tongue is pressed inwardly until it enters the container side 13.

There is thus formed an effective closure for the container.

lVhen access to the container is desired, a tool, as 20, 'isinserted-through an opening 19 and beneath the tongue portion 17, the movement of the tool, using the side 14 as a fulcrum will thus force the tongue outwardly, this action upon each tongue releasing the device from the container without marring the latter.

It will thus be seen that my device is a complete, easily applied container closure easily removed from the container without marring the latter.

I do not limit myself to the particular size, shape, number or arrangement of parts as shown and described as these are given simply as a means for clearly describing the device of my invention.

What I claim is 1. In a container closure, in combination, a U-shaped container head; a separate fastening member having a flange fixedly attached to saidcontainer head and a side member in a plane parallel to and spaced from said container head; and a plurality of hook shaped tongues carried by said fastening member side, so positioned that each tongue may be moved inwardly through an opening in said fastening member side; said fastening member side having openings through which said tongues may be moved and having an opening upon at least one side of each tongue.

2. In a container closure, in combination, a U-shaped container head having a base, an upwardly extended side and an outwardly extended flange to said side; a fastening member having a flange fixedly attached to said head flange, and a downwardly extended side spaced from and in a plane parallel to said head side, a plurality of hook shaped tongues carried by said fastening member side, said fastening member side havinga plurality of openings through each of which the hook portion of a tongue may be passed and inserted within a container side positioned between the two said sides and said fastening member side having an opening upon at least one side of said tongue through which an inserted tool will enable the tongue'to be bent outwardly of the device.

3. In a container closure, in combination, a U-shaped container head having a base, an upwardly extended side andan outwardly extended flange to said side; a fastening member having a flange fixedly attached to said head flange and a downwardly extended side spaced from and in a plane parallel to said head side, a plurality of hook shaped tongues cut out of said fastening member side and carried by said fastening member side, said fastening member side having a plurality of openings through each of which the hook portion of a tongue may be passed and inserted within a container side positioned between the two said sides and said fastening member side having an opening upon at least one side of said tongue through which an inserted tool will enable the tongue to be bent outwardly of the device.

4. In a container closure, in combination,
